A 7"7'ORNE V6.

States This invention relates to a covering for buildings or the like and more particularly to a shingle construction which may be utilized for either the side walls or roofs of the building.

The present invention is an improvement over my application, Serial No. 562,677, filed February 1, 1956.

It is the principal object of the present invention to provide a shingle or covering for building structures made from light metal such as aluminum, tin, or the like, or a plastic material as I do not wish to be limited to any particular kind of material or to any particular size or shape of plate. In press forming materials various designs of semi-circular forms may be used in my system of application, the provision of the centering tabs and nail tabs being important features of my invention.

Other objects of the present invention are to provide a covering from sheets of material having fold lines or adapted to be folded on particular lines or press formed into these shapes as in use of such materials as plastics, fiber glass and forming said centering tabs and nail tabs, providing a centering tab and nail tabs, the nail tabs being so situated on the sheet for nailing to the building structure and the next succeeding piece of material be placed thereover to cover the nail structure; to provide a structure whereby the succeeding layers of material may be placed over the previous sheets to close the spaces between the sheets to prevent moisture from entering or passing through the sheets and thus closing the vents provided in the tabs of my previous application; to provide a shingle construction made from a flat sheet of material and folded whereby each shingle may be interlocked into one another and nailed to the roof of the building structures through tabs extending outwardly from the body of the shingle providing a nailing place beyond the folded portions of the shingle; to provide a covering of diamond or rhomboid shaped sheets wherein two points will be in vertical position, the other two will be in horizontal position when the shingles are fastened to the roof or wall structure; to provide a shingle or sheet of material or parallelogram shape having right congruent angles when placed on the wall structure; and to provide a device of this character simple and economical to manufacture.

In accomplishing these and other objects of the invention, I have provided improved details of structure the preferred forms of which are illustrated in the accompanying drawings, wherein:

Referring more in detail to the drawings:

1 designates a covering for a building structure such as the roof or siding thereof usually composed of material adapted to receive shingles or other covering material. 2 designates a sheet of material covering the features of my invention shown to be of substantially diamond shape with its side edges in right angular relation to each other (Fig. 4) adapted to be folded on lines 3, 4, 5 and 6, forming hook side members 7, 8, 9 and 10, the side members 7 and 8 being folded upwardly as shown in Fig. 2 and the side members 9 and 10 being folded downwardly. Fig. 3 shows a back view of the shingle with the side members and 10 in folded position. The opposite sides 9 and 10 are slotted as indicated at 11 and 12 and the corners extend slightly outward from the side edges forming nail tabs 13 and 14 having openings 15 and 16 for the nails to fasten the shingles to the structure (Fig. 1). The lower corner of the sheet as shown in Fig. 4 is cut on a line as indicated at 17 whereby the out line 17 forms the lower end of the side flanges 9 and 10 after being folded on the lines 5 and 6.

The centering tab 18 is formed in the sheet, shown in Fig. 6, by folding on the lines 3 and 4, turning the side members 7 and 8 upwardly and inwardly, then folding the side flanges 7 and 8 on lines 19 and 20 inwardly in a parallel relation (Fig. 6) and on fold lines 21 and 22 outwardly, until the tab 38 (Fig. 6) lies flat on the side members 7 and 3 as illustrated at 23, Figs. 1 and 2, and thereby forming a pocketlike joint of the side flanges 7 and 8 on the uppermost corner of the sheet.

The nail tab corners are then folded on lines 24 and 25, 26 and 27, and 28 and 29, respectively, and then folded on lines 38 and 31 (Fig. 9) so that the tabs 13 and 14 will lie flat as illustrated in Fig. 2 and the nail tab 13 extending to the right and the nail tab 14 to the left as illustrated in Fig. 2. With this form of folding the base 32 of the nail tabs 13 and 14 will lie on top of the side members 7 and 8, respectvely. An alternate form of folding may be accomplished by the illustration in Fig. 5 by first folding the lines 30 and 26 at the same time and line 27 so that the side member 7 will lie over the folded portions 33 and 34 then the tab folded over the edge 35 of the side member 7. This folding might be preferred in some instances as a more simple method of accomplishing such fold.

When the sheet 2 is folded as above described a structure as shown'in Figs. Zwand 3 will be ready for application to the roof or siding structure as shown in Fig. 1.

A shingle 36 as thus formed is applied to the roof structure by nails (not shown) through the Openings in the nail tabs 13 and 14 with the side hook members 7 and 8 inifolded position for receiving the next succeeding sheet 37 by placing the side edge or hook member 9 under the side edge or hook membe117 with the folded nail tab or the folded edge 38 formed on fold line thereof engaging over the member 7 and extending under the folded portion 39 (Fig. 6) or underneath the aligning tab 13 formed on the fold line 19. A sheet 40 with the hook member or side 10 engaging the hook side 8 'of the sheet 36 in like manner will be placed on the opposite side of the centering tab or pocket 18.and the covering built up in such a man ner so that thetab ls will be on the top of the structure to cover any open spaces to prevent air and moisture from scribed with the centering tab 18 exposed then the succeeding shingle or sheet member maybe centered over the center flap 18 by engaging the side members 9 and 10 on the respective sides thereof underneath the side members 7 and 8 of .the next lower shingle whereby the. slot 42 forming lower edges 44 and 45 of the side members 9 and 10 will also engage along the fold lines 24 and 25 as indicated at 46 and 47 (Fig. 2), thereby providing a rigid interlocking of the shingles and thus the shingle 48 will cover the tab 18 entirely as at 48 and the shingle may be nailed through the nail tabs 13 and 14 as above shown. The shingles are connected as above described until the entire building or roof structure is covered.

In Fig. 10 I have illustrated a slightly different form of my invention whereas the sheet is of substantially diamount shape but whereby the upper and lower angles are greater than the left and right angles of the sheet thus requiring a slightly different fold. In this sheet numbered .50 the sides forming hook members are the I same as the invention shown in Fig. l and are given like numbers. The fold lines are shown in dotted lines as indicated at 51, 52, 53 and 54, the lines 51 and 52 running parallel to each side edge 55 and 56 to a point as indicated at 57 and 58 and thence outwardly to the side edges 55 and 56 of the sheet as indicated at 59 and 60. The fold lines 53 and 54 run from the notch 61 to the corners 62 and 63 of the sheet and fold lines 64 and 65 intersect .at the points 57 and 58 and extend to the side edges 55 and 56 at an angle to lines 59 and 60. Notches 66 and 67 are formed in the lower side edges of the sheet and nail tabs 68 and 69 extend outwardly from the side edges of the sheet. The fold lines 51 and 52 cross each other as indicated at 70 and fold lines 71 and 72 extend from that point outwardly at a right angle to the upper side edges 55 and 56 of the sheet for folding of the centering tab 73.

In folding the sheet as shown in Fig. lfl the sides 9 and 10 are folded downwardly and inwardly on the lines 53 and 54 and the side members 7 and 8 are also folded npwardiy and inwardly on the lines 51 and 52. The cen ter tab 73 is formed by folding on the lines 71 and 72 after the side members 7 and 8 are folded as indicated in Fig. 11. It will be seen that the fold lines 51 and 52 from the point .70 to the side edges are bent as indicated at-74,'Pig. 11. Before the side member 7 is completely folded the corner nailing tab 68 is formed by bending upon the fold lines 24 and 64. The side member 7 is then bent on lines 51 and 59 upwardly and inwardly to lie over a portion of the sheet. The sheet is then bent on the line 54 from the slot 66 to the corner edge 62 of the sheet and turned outwardly so that the tab 68 will extend outwardly from the side face of the sheet as indicated in Fig. 13. The tab 69 is formed in the same manner as 68 by folding on the lines 25 and 65 and lines 53 and 6 respectively.

The manner of assembling the shingles on the roof or building structure is the same as in the form of invention shown in Fig. 1.

Figs. 14, l5, l6 and 17 show a still further modified form of the invention wherein a sheet of material is substantially in the shape of a parallelogram comprising a sheet of material 75 having side edges 76, 77, 78 and 79 with four fold lines spaced from said side edges as indicated at 80, 81, 82 and 83. The lines 80 and 81 running from the side edges 76 and 77 to a point as indicated at 84 and 85 and there intersecting lines 86 and 87 extending in a right angle from the edges 76 and 77 and then angle to the corner of the sheet as indicated at 88 and 89. Lines 82 and 83 intersect notches 90 and 91 and the lower left hand corner is notched as indicated at 92 forming side or hook members 93 and 94 folded on the lines 82 and 83. The sheet may also be folded on the lines 80 and 81 forming side or hook members 95 and 96 as in the previous forms of the invention. The side members 95 and 96 being turned upwardly and inwardly and the side members 93 and 94 being turned downwardly and inwardly.

The centering tab 73 is formed in this form of the invention by folding of the side members 95 and 96 on the fold lines 80 and 81 and on fold lines 98 and 99, the centering tab being numbered 97 as illustrated in Fig. 15 and the lines 80 and 81 forming the folded edges as indicated at 100, Fig. 15. Corner or nail tabs 101 and .162 are provided by folding on the fold lines 82 and 83 from the notches 90 and 91 to the edge of the sheet and on lines 86, 88 and 24, respectively, of the tab 101, and 87, 89 and 25 of the tab 102 so that the tabs 101 and 102 will lie fiat over the hook members 76 and 77 as illustrated in Fig. 17. The folding of the nail tabs being illustrated as best shown in Fig. 16.

In assembling the shingles on a wall structure or roof of a building the hook members engage the respective shingles as illustrated in the form of the invention shown in Figs. 1 to 9, inclusive, and the side edges will form right congruent angles so that the nail tabs will be formed to hook under the centering tab 97 as illustrated in the preferred form of the invention as thus the centering tab will be completely covered to aid in laying the shingles in a straightline and to close the vent between the shingles thus preventing moisture and rain from entering underneath the shingles. With this form of the invention the shingle may be laid along the straight side edges of a roof or building structure so that there need be no cutting of theshingles in placing them on the structure.

nwni be obvious from the foregoing that I have provided an improved shingle cut and folded from a single piece of material such as aluminum or other like metal or plastic which would be economical to manufacture and etficient in operation.
